Is E constant in simple Gaussian diagram?

In summary, the conversation discusses how to determine if [E] is constant or varies in a simple spherical Gaussian diagram. The participants consider if the length of the arrows or their spacing indicate variation, and if there is a standard convention for indicating this in a diagram. One participant suggests scanning and posting the diagram, but the other is unable to do so. The diagram is described as a circle with evenly spaced arrows pointing outward from the center and ending outside the circle, with some arrows being slightly longer than others.

Homework Statement



If you have a simple Gaussian diagram of spherical shape, and arrows pointing out from the centre indicating [E] how do you know if [E] is constant or if it varies?

Is it because the arrows are of slightly different lengths? (Though all eminating from the centre and going out past the circumference.) Does this indicate variation?

Or would variation be indicated by arrows in different areas being more tightly together than other areas?

Thank you.

It depends upon what convention was used when the drawing was made.

Unfortunately I don't have a scanner to hand.

But if I can describe it, it's simply...

A circle with arrows all pointing out from the same point at the circle centre, and all ending once outside the circle. They all seem evenly spaced apart from each other.

However, even though they all end once outside the circle, some of them are slightly longer than others.
 

1. What is E in a simple Gaussian diagram?

E in a simple Gaussian diagram refers to the energy of the system, which is a measure of the potential energy of the particles in the system.

2. Why is E constant in a simple Gaussian diagram?

E is constant in a simple Gaussian diagram because it is assumed that there is no external force acting on the system, and thus the energy of the system remains constant over time.

3. Is E equal to the total energy of the system in a simple Gaussian diagram?

Yes, E is equal to the total energy of the system in a simple Gaussian diagram. Since there is no external force, the total energy remains constant and is represented by E.

4. How is E related to other variables in a simple Gaussian diagram?

In a simple Gaussian diagram, E is related to other variables such as temperature and volume through the ideal gas law, which states that the product of pressure and volume is directly proportional to the product of temperature and the constant E.

5. Does E change if the system undergoes a phase change in a simple Gaussian diagram?

No, E does not change during a phase change in a simple Gaussian diagram. The energy remains constant and only the temperature and volume of the system change.
